AP Diaphram

Recommended Posts

Hey Guys,

Does the side of the diaphragm with the longer shaft go towards the pump cover or carb?????? Darn thing came flying out before I could see.

Thanx,

Roach

The pictures below show the bottom side of 2 diaphrams facing up. The left one is from a crf and the right from a KTM. The shaft on the diaphram keeps it from bottoming out on the AC cover. To answer your question, the long side goes down. Also, if there is rust on one side of the diaphram, that side goes up since water can enter from above but there is only fuel below it.
